What screen resolution is Chameleon using?

<< < (2/2)

FYI:
screen_width/screen_height is the res of the bootselector
boot_width/height is the res of the boot screen (apple & spinner)
Graphicsmode is only used for the final mac os x gui.

Most modern graphicscards only have 4:3 res. (this is because vesa is hardly used anymore/drivers use other access ways). Im not sure if u can mod the vbios?

So, if u don't have an 16:10 option in ur vesa, u'll have to either use stretched images or fix them urself.
this might be cured if someone manages to port 915resolution.c to NV/ATI cards.

Thanks for the info diebuche.

Another thing i found:

The res. which is used will never be bigger than either the native screen res or the requested screen_width/screen_height size.

Two examples to clarify:

Your monitors native res: 1680x1050 (16:10)
screen_width X screen_width in Theme file = 1920x1080 (16:9)

resulting size: next lower/equal vesa mode -> 1400x1050 (4:3)


Your monitors native res: 1680x1050 (16:10)
screen_width X screen_width in Theme file = 1280x960 (4:3)

resulting size: next lower/equal vesa mode -> 1280x960 (4:3)

Hey blackosx,
I found a way to patch the VBIOS to support any widescreen resolution.
Right now it is only usable by flashing the card, but I'll work at implementing it into Cham to patch the vbios on the fly.
